[ Summary ] Clinical evidence of serrated adenoma (SA), is often seen in men with an average age of 55.1 - 63.0 years old. It is mainly located in the sigmoid colon and rectum. The frequency of SA was 0.87 - 3.3 % in cases of colonic neoplastic lesions. The average mean diameter of SA was 8.6 - 10.3 mm. Redness and uneven surfaces are useful in the discrimination of hyperplastic polyp (HP) with conventional colonoscopy. A peculiarity of the surface structure is that the cerebriform has a scaly appearance or a “pinecone” appearance. We may increase diagnostic accuracy with magnifying colonoscopy by recognizing lobes with fern like structures. We concluded that SA should be treated in the same way as normal tubular adenoma.
